文章通过分析非线性失真对场倒置加扰信号的影响，指出了非线性失真是引起解扰后图象色度（亮度）闪烁的一个不容忽视的原因。它的大小，将直接影响此类加扰方式的效果。
By analyzing the influence of nonlinear distortion on field inversion scramble signals, the paper points out that nonlinear distortion is the reason that can not be neglected to cause the chroma of image (brightness) to flicker after the descrambling. Its size will directly affect the effectiveness of such scrambling methods.
